Hello IronPython Community,
We have just released IronPython 1.0 Beta 2. The focus of this release was fixing bugs that you found and reported (big thanks!), cleanup and re-factoring of the code base and we also made significant progress towards cleaning up FxCop warnings.
You can download the release from:

We responded to the major bugs you discovered with the interactive console in the beta 1 release by dramatically improving our test coverage for this scenario. We now run our test suite both in a normal mode and in a mode that simulates the interactive console. This should prevent future regressions that only appear at the console.
Finally we also continue to improve compatibility with CPython. IronPython now passes all of test_types, test_format, and test_time in addition to the the 28 standard regressions tests that we passed without modifications in beta 1.
We'd like to thank everyone in the community for your bug reports and suggestions that helped make this a better release: Brandon Furtwangler, Catalin Lungu, David Richter, Erin Renshaw, Greg Chapman, Hector Miuler Malpica Gallegos, J. Merrill, jdehooge, Jeff Griffiths, Jonathan Jacobs, Nicholas Jacobson, Oonuki Makoto, paparipote, Paul Viola, Sanghyeon Seo, Steven Drucker, Sumit Basu and Szymon Kobalczyk
Thanks and keep in touch,
The IronPython Team
